Key Features of Ball Screws
- Low Friction Loss, High Transmission Efficiency:With many balls rolling between the screw shaft and the screw nut, high motion efficiency is guaranteed. This dramatically reduces the driving torque to less than one-third of the past sliding screw pairs, leading to energy efficiency.
- High Precision:The SFS1610 ball screw is produced with the world’s highest level of mechanical equipment, ensuring precision throughout all phases – grinding, assembly, and inspection. Strict control over temperature and humidity during the manufacturing process further ensures superior quality.
- Allows High-Speed Feed and Micro Feed:Thanks to the rolling motion of balls, the SFS1610 requires minimal starting torque, eliminating crawl phenomenon typically seen in sliding motion, thereby ensuring precise micro-feeding.
- High Axial Rigidity:By applying preload, axial clearance can be negative, thereby achieving higher rigidity. The rigidity is further enhanced due to the repulsive force of the balls when the ball screw is used in mechanical devices.
- No Self-locking Feature, Demonstrates Reversibility in Transmission:The SFS1610 2.778mm Quiet Heavy Duty Ball Screw, lacking a self-locking feature, offers reversibility. This enables efficient conversion between rotational and linear motions, enhancing application flexibility and control. Its reversibility broadens its usage, especially in precision bidirectional control scenarios.
Composition and Classification of Ball Screws
Ball screws consist of a screw, nut, steel balls, preload piece, reverser, and dust protector. They can be classified into:
- Self-lubricating Ball Screws: These eliminate the need for lubrication pipelines and equipment, reducing oil change and waste oil disposal costs.
- Silent Ball Screws: We use special groove ball spacers to minimize the noise that ball collisions produce, which results in a smoother and quieter operation of the ball screw.
- High-speed Ball Screws: We design these for applications requiring high acceleration, high rigidity, high-speed feeding, and low vibration and noise. You can find them in rapid feeding tool machines, high-speed cutting center machines, and high-speed vertical load cutting centers, among other areas.
- Heavy-duty Ball Screws: These are capable of withstanding larger axial loads and are suitable for all-electric design machines, air compressors, semiconductor manufacturing devices, and forging manufacturing devices.
Parameters
- Nominal Diameter:The nominal diameter refers to the outer diameter of the screw, with common specifications being 12, 14, 16, 20, 25, 32, 40, 50, 63, 80, 100, 120.
- Lead:Lead refers to the distance the screw nut moves linearly when the screw rotates one revolution. The lead is related to the nut movement speed and the linear thrust the ball screw can provide. With larger leads, the linear movement speed is faster at the same rotation speed.
The relationship between lead, screw thrust, and motor torque can be defined as follows:
F=（2πT*n）/i
Where: F: Screw thrust (N) T: Torque provided by the motor (N.m) n: Transmission efficiency (85%-95% for ball screws) i: Lead (m)
- Length:Length consists of the total length and thread length. Manufacturers sometimes need to know the thread length, which they can further break down into total thread length and effective stroke. The total thread length includes the total length of the threaded part, and the effective stroke refers to the maximum theoretical linear movement length of the nut.
- Nut Shape:The nut shape is typically indicated by the first few letters of the model. There are several types of flanges, including round flanges, single-cut flanges, double-cut flanges, and no flanges.
- Precision:The precision level of ball screws in China are classified into P1, P2, P3, P4, P5, P7, P10. In Japan, Korea, and Taiwan, the JIS level is adopted, namely C0, C1, C2, C3, C5, C7, C10. European countries follow the IT0, IT1, IT2, IT3, IT4, IT5, IT7, IT10 standard.
The ZLV SFS1610 2.778mm Quiet Heavy Duty Ball Screw embodies these parameters and features, making it a reliable component in precision-driven systems. Its robustness, efficiency, and customization options make it an exceptional choice for a diverse array of applications.
